一个修改RAC REDO引起的DATAGUARD错误 的处理

前几天RAC出现错误。引起Configuration 异常。

后调整RAC 的REDO文件大小。

今天看到STANDBY 端出错，错误如下：

1、FRIMARY SERVER:

在RAC PRIMARY 端，先关闭日志同步。

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=defer;

System altered.

2.暂停STANDBY

SQL> alter database recover managed standby database cancel;

Database altered.

3.修改模式：

SQL> alter system set standby_file_management=manual;

System altered.

4.删除并重新建立日志，

这里遇到一些问题，有些日志重启STANDBY服务器及重启/关闭日志同步2次后，再重新建立成功。

SQL> alter database drop logfile group 1;

alter database drop logfile group 1
